    55This page uses gcf 2.0 or higher to demonstrate a GENI Experiment. If you are using gcf 1.6.2 or earlier, see the [http://groups.geni.net/geni/wiki/GENIExperimenter/ExperimentExample Experiment Example] using gcf 1.X tools.

    7 This page illustrates an operational example for the [wiki:HowToUseOmni Omni How-to] page capturing the actions required to run an experiment using multiple resource aggregates and with user credentials from the GPO ProtoGENI Clearinghouse pgeni.gpolab.bbn.com. Details on how credentials are set up can be found in the [wiki:HowToUseOmni#a1.GetGENICredentials GENI Credentials] section of the main [wiki:HowToUseOmni Omni How-To] page. In this experiment, a total of 5 nodes are requested, with 2 nodes from the Emulab (PG) aggregate and 3 nodes from the !PlanetLab (PL) aggregate.

    174 Note in the above output that our new slice expires soon. Any resources that you will reserve as part of your slice can not last longer than your slice, and will go away when the reservation expires. For your experiment be sure to renew your slice for the duration of your experiment. Here we only slightly extend the slice lifetime.

For PlanetLab, notice the value in the 'pl_login' field, which is the login to be used to access the nodes. For a slice across multiple aggregates, you should pay close attention to the expiration time for each aggregate sliver (pg_expires & pl_expires).  Note that slice expiration time is also available in the output of many commands.

     438Review the output file and check for the '' "geni_status" '' to be '' "ready" '' to verify that the requested compute resources are ready for use.  A lot of very useful information is reported for the ''sliverstatus'' output including which hosts are assigned to you and for how long. For !PlanetLab, notice the value in the 'pl_login' field, which is the login to be used to access the nodes. For a slice across multiple aggregates, you should pay close attention to the expiration time for each aggregate sliver (pg_expires & pl_expires).  Note that slice expiration time is also available in the output of many commands.
    585439
    586440Also note that by using the ''aggregates'' option in your ''omni_config'', you can configure Omni to talk to all the aggregates in your experiment, and only those aggregates. Then ''sliverstatus'' will get full status for you in a single call.
    587441
    588 Note that the Emulab PG aggregate limits slivers to a duration of 5 days and you may need to extend the sliver expiration.  For this example the pg_expires is ''2012-01-14 11:10:10'' while the pl_expires is ''2012-01-23T13:12:32Z''. Make sure that each expiration time meets your requirements for your experiment's duration.  If you need to extend the expiration, you can use the Omni ''renewsliver'' to extend each sliver. The following command is issued to modify the expiration time for the ProtoGENI resources:
